Suggestion box in GenStat!

Dear PR responsible,

First of all... sorry, this got bigger than expected. This PR adds a page Suggestion Box to Genomics Status, that replaces the Google Docs form.

Secondly, I removed old code from Amanita and Picea pages, as well as some references to other databases that I'll remove when this gets merged in production.

Notes about this PR:
* This is the work around for: https://trello.com/c/bG9yVkaZ/328-new-turn-to-the-suggestion-box
* The files `jquery.validate.js` and `spin.min.js` are javascript plugins that you **do not** need to review.
* Below some screenshots, but it is deployed in https://genomics-status-stage.scilifelab.se as well (Click on your username on the right top corner to go to the suggestion box). So, feel free to find bugs, I'll be happy to fix them. Everything will go to tools-dev, that I'll wipe out once this gets merged, as well as the trello board.

Hooray! This dropdown has been bugging me for ages. I [also got rid of it](https://github.com/ewels/status/commit/bcf5674b0e02854c4ac9260574fd36bc007d724a#diff-249c33414a6b43a0941f85b3cf6c84d2R92) in my refactoring ;)

Merging my branch is going to be horrible..
